Description

[Technical Field]

[0001] The present invention relates to a package and a method for opening the package, and more particularly to a package in which a film packaged product is attached to a paper sheet member such as a mount, and a method for opening the package. [Background technology]

[0002] For example, to present a product with a curved outer periphery, such as a cylindrical outer periphery, in an attractive manner, it is effective to hang the product. Patent Document 1 below discloses a package in which a tubular shrink film is bonded to the surface of a mount by a bonding means such as an adhesive, adhesive tape, or heat welding to form a shrink film-attached mount, and with a product (packaged item) having a cylindrical outer periphery housed inside the tube, the shrink film is thermally shrunk to attach the packaged item to the mount. The package can be hung and displayed by passing a beam-shaped rod member through a hole provided in the top of the mount. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-168447 [Patent Document 2] Patent No. 7052961 Summary of the Invention [Problem to be solved by the invention]

[0004] In this type of packaging, in which a film package is attached to a sheet member such as a backing, perforations are often provided in the film covering the packaged item, and the packaged item (product) can be removed by tearing and peeling the film along the perforations. Some packages also have a knob-like protrusion on the edge of the film near the perforations that can be used to pick up and pull after scratching with a fingernail. However, in the latter case, the protrusion is difficult to scratch with a fingernail, and both the film and the protrusion are difficult to find, making it difficult to tear the film and remove the packaged item (product).

[0005] The present invention has been made in consideration of the above-mentioned problems, and its object is to provide a package and a method for opening the package that make it easy to tear the film enclosing the packaged item, thereby making it easy to remove the packaged item, such as a product. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, one aspect of the packaging body of the present invention is a packaging body in which a film covering the packaged item is attached to a paper sheet member, thereby attaching the packaged item to the sheet member, and the film has a film fragile portion on the surface facing the sheet member where it is not attached to the sheet member, which allows the film to begin to tear.

[0007] In a further aspect of the present invention, double-sided tape is continuously attached over a predetermined length in a predetermined direction on one side of the sheet member, and the packaged item is attached to the sheet member by attaching a film to the double-sided tape, and the film fragile portion is provided at a location that extends in the continuous direction of the double-sided tape and is not attached to the double-sided tape on the surface of the sheet member.

[0008] In a further aspect of the present invention, the sheet member is provided with a sheet fragile portion between the film fragile portion and the double-sided tape for folding the sheet member to the side opposite the packaged item, and the sheet fragile portion is linear and extends in a direction intersecting the continuous direction of the double-sided tape.

[0009] When opening this package, the sheet member is folded along the sheet fragile portion toward the side opposite the packaged item, and the folded portion is pulled toward the side opposite the packaged item, causing the film to tear along with the double-sided tape from the film fragile portion. [Effects of the Invention]

[0010] According to the present invention, the film enclosing the packaged item can be easily torn, and as a result, the packaged item, such as a product, can be easily removed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Embodiments of the packaging body of the present invention will be described in detail below with reference to the drawings. The embodiments shown below are merely examples of configurations and methods for embodying the technical concept of the present invention, and the technical concept of the present invention is not limited to the materials, shapes, structures, arrangements, etc. of the components of the embodiments described below. Furthermore, the drawings are schematic. Therefore, it should be noted that the relationship and ratio between thickness and planar dimensions may differ from the actual ones, and the drawings may also contain portions where the relationship and ratio of dimensions differ from each other.

[0013] The package of the embodiment shown in FIG. 1 has a film package 2 attached to one side of a backing sheet 1, which is a paper sheet member, and is similar to the package described in Patent Document 1. The film package 2 is a packaged item 3, such as a hygienic product, wrapped in a shrink film 4. In this example, the entire periphery of the packaged item 3 is covered with the shrink film 4. The actual shrink film 4 is very thin, and is shown schematically here as being in close contact with the packaged item 3. A product (packaged item 3), such as a hygienic product, can be displayed attractively by attaching the film package 2 to the backing sheet 1 and hanging it from a beam-like rod inserted through a hole 11 in the upper part of the backing sheet 1. In this example, the shrink film 4 does not necessarily cover the entire surface of the packaged item 3, as long as the packaged item 3 is not easily removed from the backing sheet 1. Furthermore, a film other than the shrink film 4 may be used. Furthermore, "made of paper" includes not only paper itself but also materials that are mainly made of paper.

[0014] As shown in the front view of Fig. 1, the packaged item 3 in this embodiment is, for example, a rectangular parallelepiped shape that is elongated in the vertical direction, and as shown in the plan view of Fig. 1, its rectangular cross section is slightly wider than it is deep. Furthermore, this packaged item 3 has a recessed portion (through-hole) 3a with an oval cross section that penetrates the cross section in the depth direction at the bottom end of the front view of Fig. 1. Furthermore, when removing the packaged item 3, which is a sanitary product in this embodiment, from the package, it is desirable to remove it from the bottom end side of the front view of Fig. 1 due to the product configuration.

[0015] As shown in FIG. 2a, the backing sheet 1 used in the package of this embodiment has a crease 6, called a fold crease, formed continuously along the entire length of the backing sheet 1 in a predetermined direction (in this example, a rectangular backing sheet 1 in a plan view) at a location near the end opposite the hole 11 in the longitudinal direction of the backing sheet 1, and this crease 6 of the backing sheet 1 constitutes a sheet fragile portion. In the figure, the crease 6 is indicated by a two-dot chain line. This crease 6 is formed by linearly compressing the backing sheet 1 in the thickness direction, thereby linearly indenting the paper material. This indentation serves as a fragile portion, making the backing sheet 1 easier to fold. Before laminating the film package 2 to the backing sheet 1, a predetermined length of double-sided tape 5 is attached to the backing sheet 1 in a predetermined direction, as shown in FIG. 2b. As described below, half-cut double-sided tape is used as this double-sided tape 5, and the continuous application direction of this double-sided tape 5 is a direction intersecting, preferably perpendicular to, the continuous application direction of the crease 6. One end of the double-sided tape 5 in the continuous application direction is positioned approximately at the position of the ruled line 6 in the widthwise center of the backing sheet 1, and the double-sided tape 5 is applied to the backing sheet 1 from there toward the hole 11. The double-sided tape 5 may be applied to the backing sheet 1 in any direction along the tape's length. Then, as shown in FIG. 2c, the film package 2 is applied to the double-sided tape 5 so that the length of the elongated packaged item 3 (film packaged item 2) coincides with the continuous application direction of the double-sided tape 5 and one side in the depth direction faces the backing sheet 1. Essentially, the shrink film 4 covering the packaged item 3 is applied to the double-sided tape 5, and the film packaged item 2 (packaged item 3) is applied to the backing sheet 1.

[0016] As described above, in this embodiment, half-cut double-sided tape is used as the double-sided tape 5. As shown in FIG. 3, half-cut double-sided tape is obtained by cutting the double-sided tape 5 into small pieces at predetermined intervals along the longitudinal direction, and is disclosed, for example, in Patent Document 2. The automatic application device for half-cut double-sided tape described in this patent document applies the double-sided tape 5 (only) to the backing sheet 1 by pressing the half-cut double-sided tape with a liner unwound from a roll against the backing sheet 1 with an application roller. While the half-cut double-sided tape is in contact with the backing sheet 1, small pieces of the double-sided tape 5 are applied one after another to the top surface of the backing sheet 1 as the application roller rotates due to the relative movement of the double-sided tape 5 and the backing sheet 1. However, when the half-cut double-sided tape separates from the backing sheet 1, the small piece of the double-sided tape 5 that was in contact with the backing sheet 1 immediately before the separation is cut off at the half-cut position of the double-sided tape 5, and the remaining small pieces of the double-sided tape 5 remain on the liner. The half-cut double-sided tape in Figure 4 has wavy mountain-shaped half-cut lines, but there are also other types of half-cut lines.

[0017] As mentioned above, half-cut double-sided tape does not require a step of cutting the double-sided tape 5. For example, if the double-sided tape application process shown in Figure 2b is performed using an automated machine, including a step of cutting the double-sided tape 5, cutting the double-sided tape 5 takes time, even if only slightly, which may make it difficult to manufacture the package shown in Figure 2 within a short takt time. Furthermore, when cutting a strip-shaped material with adhesive components, such as the double-sided tape 5, there is a problem that the adhesive components adhere to the cutting tool (cutting means) blade, causing the blade to become dull. Once the blade becomes dull, the manufacturing equipment must be stopped and the adhesive components must be removed from the blade. Since half-cut double-sided tape does not require a step of cutting the double-sided tape 5, these problems do not arise. In reality, the double-sided tape 5 is so thin that it is invisible when viewing the package from the side or above. Figure 1 schematically illustrates the double-sided tape 5. Furthermore, adhesives, thermal adhesives, etc. may be used instead of the double-sided tape 5 to attach the film package 2 to the backing sheet 1.

[0018] In this embodiment, a small hole (so small that it is invisible to the naked eye) is formed in the shrink film 4 on the backing sheet 1 side at the location of the recessed portion 3a of the packaged item 3, and this hole constitutes the film fragile portion 7 where the shrink film 4 begins to tear. This film fragile portion 7 is the location marked with an "x" in the front view of FIG. 1 and the location marked with an arrow in the left side view of FIG. 1. If the film-packaged item 2 (packaged item 3) is attached to the backing sheet 1 using double-sided tape 5, this film fragile portion 7 must be a portion of the shrink film 4 extending in the direction of the double-sided tape 5 and not attached to the double-sided tape 5 on the backing sheet 1 side. If the film-packaged item 2 (packaged item 3) is not attached to the backing sheet 1 using double-sided tape 5, then the film fragile portion 7 must be a portion of the shrink film 4 that is not attached to the backing sheet 1 side. However, in either case, it is preferable that the portion be located not far from the area where the shrink film 4 is attached to the backing sheet 1. Also, scratches, perforations, etc. may be used instead of holes. For example, if a hole is formed after the shrink film 4 has been wrapped around the outer periphery of the packaged item 2, the packaged item 2 must be recessed where the hole is to be formed, but if the hole is a scratch, the packaged item 2 does not need to be recessed. Also, if perforations are provided in the shrink film 4 beforehand, the process of punching holes or scratching the shrink film 4 before laminating the film-packaged item 2 to the backing 1 is not necessary.

[0019] When removing a packaged item 3, such as a product, from the package of this embodiment, for example, as shown in Fig. 4a, the backing sheet 1 is folded along the line 6 toward the side away from the packaged item 3 (film package 2), and then, as shown in Fig. 4b, the folded portion of the backing sheet 1 is pulled toward the side away from the packaged item 3 (film package 2) while inserting, for example, the tip of a finger between the backing sheet 1 and the film package 2. As a result, the shrink film 4 begins to tear at the weakened portion (hole) 7 of the film. When the folded portion of the backing sheet 1 is further pulled toward the side away from the packaged item 3 (film package 2), the portion of the shrink film 4 that is attached to the double-sided tape 5 is torn along the double-sided tape 5 and separated from the surrounding area, as shown in Fig. 4c, and the portion of the packaged item 3 facing the backing sheet 1 is exposed from the shrink film 4 (the bag-shaped portion). Once the portion of the packaged item 3 facing the backing 1 is exposed in this way, the packaged item 3 is removed from the portion that is covered in the bag-like shape by the shrink film 4. If the film fragile portion 7 is located away from the area where it is attached to the backing 1, when the shrink film 4 is pulled and begins to tear at the film fragile portion 7, the shrink film 4 will stretch (a lot) between the film fragile portion 7 and the area where the shrink film 4 is attached to the backing, and the stress required to tear the shrink film 4 from the film fragile portion 7 will be reduced, making it less likely to tear.

[0020] FIG. 5 shows a perspective view of a modified example of the package shown in FIG. 1 , and FIG. 6 shows its left side view. The packaged item 3 in this modified example is cylindrical and has a relatively large outer diameter. As in the example shown in FIG. 1 , the entire circumference of the packaged item 3 is pre-covered with a shrink film 4 to form a film package 2. The backing sheet 1 in this modified example has a hanging hole 11, as in FIG. 1 , but is also configured to allow the packaged item 3 (film package 2) to stand upright. In this example, too, a ruled line 6 is provided in the area indicated by the two-dot chain line in FIG. 5 , and double-sided tape 5 is affixed to the backing sheet 1 from the ruled line 6 toward the hole 11. The double-sided tape 5 is half-cut. A film fragile portion 7, such as a scratch, is formed in the shrink film 4 at the portion extending in the continuous direction of the double-sided tape 5 and not attached to the backing sheet 1 by the double-sided tape 5. This is the portion indicated by the "x" in FIG. 5 and the arrow in FIG. 6 . In this example, the film package 2 (item 3) is attached to the backing sheet 1 so that the bottom edge of the film package 2 (item 3) is at the same height as the bottom edge of the backing sheet 1 or the former is slightly lower than the latter. Therefore, the package can stand on its own using the bottom surface of the film package 2 (item 3). The procedure for removing the item 3 from the package is the same as that shown in Figure 1.

[0021] In this way, in these embodiments, when the shrink film 4 covering the packaged item 3 is attached to the backing sheet 1 to form the package, a film fragile portion 7 is provided on the surface of the backing sheet 1 that is not attached to the backing sheet 1, at which the shrink film 4 begins to tear.By doing this, when the backing sheet 1 is pulled away from the packaged item 3, the shrink film 4 tears at the film fragile portion 7, allowing the packaged item 3 to be removed.

[0022] Furthermore, when double-sided tape 5 is continuously attached over a predetermined length in a predetermined direction on one surface of backing sheet 1 and shrink film 4 is attached to this double-sided tape 5 to attach packaged item 3 to backing sheet 1, by providing a weak film portion 7 at the extension point of the double-sided tape 5 in the continuous direction and at a portion on the backing sheet 1 side that is not attached to the double-sided tape 5, when backing sheet 1 is pulled away from packaged item 3, the shrink film 4 that begins to tear from the weak film portion 7 will tear along the double-sided tape 5, exposing packaged item 3 from the shrink film 4 (bag-shaped portion), and packaged item 3 can be easily removed.

[0023] Furthermore, by providing a line 6 between the weak part 7 of the film and the double-sided tape 5 for folding the backing sheet 1 away from the packaged item 3, the backing sheet 1 can be folded at the line 6 away from the packaged item 3 before the shrink film 4 is torn, and the folded part can be held and the backing sheet 1 can be easily pulled in the direction away from the packaged item 3.

[0024] Although the above describes the packaging body according to the embodiment, the present invention is not limited to the configuration described in the above embodiment, and various modifications are possible within the scope of the gist of the present invention. For example, in the above embodiment, the double-sided tape 5 is attached to the backing sheet 1 along the longitudinal direction of the packaged item 3, so that the shrink film 4 is configured to tear along the double-sided tape 5, i.e., along the longitudinal direction of the packaged item 3. However, the direction in which the shrink film 4 is torn does not necessarily have to be along the longitudinal direction of the packaged item 3. However, it is easier to tear the shrink film 4 along the longitudinal direction of the packaged item 3 than in any other direction. [Explanation of symbols]
